<p>The apparatus comprises a vaporising unit (1), its fluid level (2) remaining constant. A duct (4) leads off this unit, to pass through a collar (6) of friction material. At this point, a smaller tube (9) is inserted, its external end being bent 90 degrees to form a nozzle (10), fitted with a heater (13). This projects through an opening (15) in a surrounding casing (14). An ozone producing unit (16) is provided inside this and as the steam issues through the nozzle, it entrains the ozone with it. A handle (8) projects through the casing to manipulate the nozzle.</p> |
